APPARATUS FOR RAISING QUICKSAND.

SPECIFICATION forming part of Letters Patent N0. 404,741, dated June 4, 1889. I Application filed February 6, 1889. Serial No. 298,839. (No model.)

To all whom it may concern:

Be it known that I, HENRY SroLTzE, Sr., a citizen of the United States, residing at Manitowoc, in the county of Manitowoc and State of Wisconsin, have invented a new and useful Improvement in Apparatus for Raising Quicksand, of which the following is a specification.

My invention relates to an improvement in apparatus for raising quicksand from wells and other excavations; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is an elevation of an apparatus embodying my improvements. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a cross-sectional view taken on the line (I; as of Fig. 2.

A represents a casing, which is circular in cross-section and is tapered in form, being of greater diameter at its base. The lower end of the said casing is open and the upper end thereof is covered by a conical cap B. The said cap is provided at its apex with an opening 0, and on opposite sides of the cap are openings D.

E represents valves which are hinged on the sides of the cap, are weighted, and are adapted to normally close on the openings E. The said cap is further provided on opposite sides with a pair of handles F.

G represents a rod, which extends down through the opening 0, and attached to the lower end of the said rod is a screw-bladed boring-bit H. Rigidly secured to the rod G at a suitable height above the boring-bit is a collar 1, which is adapted to engage the under side of the cap B when the boring-bit is raised to such a height as to be just within the lower end of the case. An opening K is made transversely through the rod G at a slight distance above the collar I, and a pin or key L- is adapted to be inserted in the said opening above the cap and thereby lock the boring-bit within the case to prevent the rod G from moving longitudinally in the case and yet permit the said rod, together with the boring-bit, to freely rotate. Attached to the upper end of the rod G is a squared offset M, which is adapted to be engaged by the socket When the key is in position in the opening K and the boring-bit arranged in the lower end of the case, the latter is lowered'to the bottom of the 'well or excavation and the screw-bladed bit is rotated in the direction indicated by the arrow in Fig. 3, which causes the said screw-bladed bit to bore its way down into and through the quicksand and to force the casing downward therein until the casing becomes entirely filled with sand. As the case descends the accumulated pressure therein forces the water from the quicksand in the case out through the openings D past the valves E. 'When the case is filled to the limit of its capacity, the apparatus is withdrawn to the surface by means of the rope a, the key is withdrawn from the opening K, and the rod and boring-bit caused to descend by their own gravity and the weight of the material in the case, and the latter is thereby discharged. from the case, as will be very readily understood.

Having thus described my invention, I claim 1. The combination of the tapered case having the outwardly-openin g valves at its upper end, the rod revoluble 'in the case, and the boring-bit attached to the said rod and arranged in the lower end of the case, substantially as described.

2. The combination of the tapered case havin g the valves at its upper end, the rod revoluble in the case and having the boring-bit at its lower end, means, substantially as set forth, to rotate the said rod, the plate N, pivotally connected to the said rod, and the elevatingrod attached to said plate, substantially as described.

3. The combination, in apparatus for rais- IEO ing quioksand, of the case having the valves at its upper end, the rod G, extending through an opening in the upper end of said ease and revoluble therein, said rod having the collar I, adapted to bear under the top of the ease, and the opening K above said collar, the boring-bit attached to the lower end of the rod and arranged in the bottom of the ease, and the pin or key adapted to be inserted in the openingK, substantially as described.

at. The combination of the tapered ease having' the outwardly-opening valves at its upper end, the rod revoluble and longitudinally movable in the ease, and the boring-bit attached to the rod and arranged in the lower end of the ease, substantially as described.

In. testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
